please answer the following question who will answer correct I will give it brainlist....​

Answer 1

formula length × breath

a) length = 10m × breadth = 12m

10m × 12m

120

so, a) answer is 120m

Answer 2

Step-by-step explanation:

Solution :-

a)

Given that

length of the rectangle (l) = 10 m

breadth of the rectangle (b) = 12 m

We know that

Area of a rectangle is lb sq.units

Area of the given rectangle

=> A = 10×12 m²

=> A = 120 m²

Area of the rectangle = 120 m²

b)

Given that

length of the rectangle (l) = 30 cm

We know that

1 cm = 10 mm

30 cm = 300 mm

l = 300 mm

breadth of the rectangle (b) = 150 mm

We know that

Area of a rectangle is lb sq.units

Area of the given rectangle

=> A = 300×150 mm²

=> A = 45000 mm²

or

100 mm² = 1 cm²

=> 45000 mm² = 45000/100 = 450 cm²

Area of the rectangle = 450 m²

c)

Given that

length of the rectangle (l) = 55 m

breadth of the rectangle (b) = 1000 cm

We know that

100 cm = 1 m

1000 cm = 10 m

We know that

Area of a rectangle is lb sq.units

Area of the given rectangle

=> A = 55×10 m²

=> A = 550 m²

Area of the rectangle = 550 m²
